Patent number: 9056964Abstract: A process for making bis(aryloxyalkyl)terephthalates useful as antiplasticizers for thermoplastic polyesters is disclosed. Dimethyl terephthalate is reacted with an excess of an aryloxyalkanol in the presence of a condensation catalyst to produce an intermediate mixture comprising a bis(aryloxyalkyl)terephthalate, a mono(aryloxyalkyl)terephthalate, and unreacted aryloxyalkanol. This mixture continues to react at reduced pressure while unreacted aryloxyalkanol is removed and the mono-ester content is reduced to less than 1 mole % based on the combined amounts of mono- and bis-esters. Both steps are performed substantially in the absence of oxygen. Additional unreacted aryloxyalkanol is then removed to provide a purified bis(aryloxyalkyl)terephthalate having an overall purity of at least 98 mole % and a yellowness index less than 10.Type: GrantFiled: February 7, 2014Date of Patent: June 16, 2015Assignee: Stepan CompanyInventors: Rick Tabor, Brian K.

Patent number: 6060625Abstract: A process for the alkoxylation of a polyetheramine to form an etheramine alkoxylate. In the process, a polyetheramine is reacted with an alkylene oxide in the presence of an alcohol to form the etheramine alkoxylate. The alcohol serves as a catalyst to allow the reaction proceed at a heightened temperature as compared to the reaction in the absence of alcohol, while at the same time limiting the amount of glycol by-product production which would otherwise typically form when higher polyetheramines are to be alkoxylated. The alcohol may be, for instance, ethanol or methanol.Type: GrantFiled: April 30, 1999Date of Patent: May 9, 2000Assignee: Huntsman Petrochemical CorporationInventors: Wei-Yang Su, Mike W. McKinney, Timothy L. Lambert, Edward T. Marquis

Patent number: 6037516Abstract: Oxygenate impurities are removed from an organic chemical feed or stream by treatment with an aqueous reducing agent and aqueous base, accompanied by separation. An aqueous solution of reducing agent and an aqueous solution of base are typically introduced sequentially into the organic chemical stream, where they may react with any oxygenate impurities present. The reaction products of the oxygenate impurities and aqueous reducing agent and aqueous base are water soluble, and are typically removed in sequential fashion via any suitable separation means. For example, oxygenate impurities such as formaldehyde, acetaldehyde, propionaldehyde, and methyl formate may be removed from a propylene stream by treating the stream sequentially with aqueous sodium bisulfite and aqueous sodium hydroxide, accompanied by separation of the oxygenate impurity reaction products in coalescers.Type: GrantFiled: November 20, 1997Date of Patent: March 14, 2000Assignee: Huntsman ICI Chemicals LLCInventors: Peter S.
